A computer system using open source software and operating systems is enabled over a global computer network to provide universal, selected applications. The applications can be accessed from a local personal computer, personal digital assistant (PDA), remote dedicated computer terminal, or like devices. Selected applications may include word processing, calendar, address book, picture viewing, music playing, games, email, Internet access, and the like. Personal data, such as pictures, music, games, "favorite places", email addresses, and application settings are saved to the local client device and to a centralized customer support server. An included software manager ensures that the most current version of each application is used, and, if not available on the client, it can be uploaded, if necessary.
